According to AU rules you are allowed to book catering for meetings with external participants.
Prior to ordering catering, you must get approval from the head of department using the MGMT expense form. The signed form must be sent to expensetravel@mgmt.au.dk prior to ordering.
If you exceed the amount of DKK 3,000 when eating at a restaurant, we must have an invoice issued to Aarhus University. A receipt or a slip is not sufficient.
You can still pay with your AU credit card and settle the expenses in RejsUd, but you must attach an invoice issued to Aarhus University.
